The annoyance when it turns out that one of the parts that arrived today wasn't the correct one:

Spot the empty space....

It is reading USB sticks though

What’s the other part for?

What’s the other part for?

It's a 74HCT74, a flip flop, and half of it seems to form part of the circuit feeding CLK to the AY chip. The other half is doing something else, but the schematics are not totally clear on what that is, though it does also seem to be CLK related.

Hmm, so looking further at the schematic, I clearly couldn't see the wood for the trees, the other half of the 74HCT74 is simply all tied to ground, so not in use.

Note to self: Sometimes stuff is just obvious, so don't over complicate!!

So, umm, do you have a definitive list of your computing collection? Or would that in itself be a huge feat?

Planning on adding an MSX and Dragon 32 soon

Watch out! Once you get the MSX bug it can be dangerous... There are *SO* many types of MSX and MSX2 machines out there, especially direct import from Japan.

I know, it's quite terrifying how may MSXs there are!!
